SIMPRO/VTT Task 2.3

Optimisation of a particle damper with DEM

Abstract

The idea of this study was to show that designing a
particle damper using optimisation is feasible with the
computational power of current parallel computers and DEM
tools. It was shown that the concept works. The Parallel
Direct Search optimisation method was able to find the
optimal configuration for the particle damper. Also the
straight forward parameter study proved to be a viable
option. On the other hand it was found that the DEM tools
need more development and that the DEM simulation is
slower than expected. Also in this study a 5 to 10 times
saving for the simulation time was found by showing that
it is not necessary to simulate until the transient peeks
due to the start are settled out.
